DEVICE'IEOR LIFTING PUSH-RODS ON FORD MOTORS.

Specification of Letters Iatent.

Patented 0013.25, 1921.

Application filed September 18, 1920. Serial No. 411,278.

To all. whom it may concern:

Be it known that l, lVi LmM T. MoCan LE1, acitizen of the United States, residing at. Luling, in the county of Caldwell and State of Texas, have invented certain new and useful Improvements in Devices for Lifting Push-Rods on Ford Motors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompany ing drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

The object of this invention is to provide an improved form of device for lifting push rods, intended more particularly for use on Ford motors, but susceptible of. use, of course, on other makes of automobiles, the lifting device being used when it is desired to position the cam shaft bearing in the Ford motors.

The invention is clearly disclosed in the accompanying drawing, in which like reference characters designate corresponding parts throughout the several views. Briefly decsribed: I

Figure 1 is a fragmentary View in side elevation, of a portion of an automobile with the device of my invention in operative position;

Fig. 2 is a view in top plan of the stationary and movable jaws and the screws carried by the movable jaws foractuating the same, and showing, in section, a pushrod clamped by a pair of said jaws, and

Fig. 3 is a collective detail view, in perspective, of the member carrying the stationary jaws, and of one of the movable jaws detached.

Fig. 4 is a top plan View of the base with the jack screw shown in section.

Referring now in detail to the drawings:

1 designates a base, which may be, of suitable form, in this instance comprising a plate having arcuate ends 2, 2.

Rising from the base is a screw 3, carrying a nut 4. j

A casting 5 is formed with a centrally recessed portion 6, adapted to receive the screw 3, and is also provided with wings 7, 7 constituting stationary jaws, and hav- ,ing curved outer surfaces 8, 8.

Carried by each of said stationary jaws 7 is an ear 9, perforated, as shown at 10.

OalCl 6&1 9 1S adapted to be pro ected into an aperture 11 in a movable jaw 12, said jaw having a curved aw face 1= As shown in detail in Fig. 3, said jaw 12 is curvecl longie tudinally. It is also provided with an opening 14, adapted, when the jaw'is disposed on the ear 9, to register with the opening 10, a pivot pin 15 passing through said registering openings and pivotally securin the inovable jaw to the. stationary jaw. ach movable :jaw is provided laterally with a screw threaded opening 16, through which an ad usting screw 14 passes, one end of said screw being adapted to bear upon the castmg 5, as shown clearly in Fig. 2, and the other end of said screw being provided with a head, or thumb piece, 18, for convenient manipulation of the screw.

In operation, the base plate 1 is positioned, as shown in F ig. 1, between two of the pushrod guides at, the arcuate ends 2, 2 of the plate engaging the guides a, which latter have a circular exterior surface. The base plate is thus held against horizontal movement.

The operator then turns the motor with a crank until one valve reaches its highest point on the cam shaft. He then loosens the thumb screws 17, 17 and disposes the stationary jaw-carrying member 5 on the screw 4 with the screw 3 in the recess 6, and clamps the push-rod A, that has been raised, as aforesaid, by screwing up upon the screw 17 carried by the jaw member 12, until the push-rod is clamped between the jaw face 13 and the corresponding, or adjacent, stationary jaw 7. Thereupon, the operator turns the motor again until the next valve rises to its highest point. He then swings the other movable jaw 12 toward this second raised push-rod, clamping the same as in the case of the first push-rod.

V The operator then takes a wrench and turns the nut 41 to elevate the same upon the screw 3, which raises the push-rods held by the cooperating jaws, as aforesaid, so that the push-rods are raised entirely off of the cam shaft B, carrying the cams b. The operator then proceeds to adjust another set of clamps to the remaining pushrods, and proceeds in the same manner as before to raise these rods off of the cam shaft. hen all of the push-rods have been 1 raised from the cam shaft, the cam shaft is left free to be pulled out of the motor and a new bearing installed.

7 said movable jaws.

The curved face 8' on ejaeh stationary jaw facilitates applicationbf the device, when actuating said movable jaws and means to lift all of saidjaw' structures as an organized unit.
